River Dee, Wales River Dee, Wales The River Dee at Llangollen Countries slopes of Dduallt above Llanuwchllyn in the mountains of Snowdonia - elevation 1,816.8 km2 (701 sq mi) Discharge 29.71 m3/s (1,049 cu ft/s) Discharge elsewhere (average) - Bala Lake 13.06 m3/s (461 cu ft/s) The River Dee ( Welsh : Afon Dyfrdwy, Latin : Deva Fluvius) is a river in the United Kingdom . It flows through parts of both Wales and England , forming part of the border between the two countries. The river rises in Snowdonia , Wales, flows east via Chester , England, and discharges to the sea in an estuary between Wales and the Wirral Peninsula in England. It has a total length of 70 miles (110 km). Contents 8 External links and further reading History The River Dee was the traditional boundary of the Kingdom of Gwynedd in Wales for centuries, possibly since its founding in the 5th century.

[1] It was recorded in the 13th century as flumen Dubr Duiu; [1] the name appears to derive from the Brythonic dēvā: “River of the Goddess” or “Holy River”. [2] Statistics The total catchment area of the River Dee down to Chester Weir is 1,816.8 km2 (701.5 sq mi). [3] The estimated average annual rainfall over the catchment area is 640 mm (25 in), yielding an average flow of 37 m3/s . The larger reservoirs in the catchment area are: Llyn Celyn : 325 acres (1.32 km2) Catchment Pontcysyllte Aqueduct carrying the Llangollen Canal ; the River Dee runs beneath. View downriver from the bridge in the centre of Llangollen (March 2007) River Dee in snow at Llangollen (February 2007) The River Dee has its source on the slopes of Dduallt above Llanuwchllyn in the mountains of Snowdonia in Meirionydd , Gwynedd , Wales.

Between its source and Bala Lake the river is known by its Welsh name, Afon Dyfrdwy. Legend tells that the waters of the river pass through Bala Lake and emerge undiluted and unmixed at the outflow. On leaving Bala the river meets its confluence with Afon Tryweryn and passes through the Bala sluice gates, part of the Dee Regulation System protecting communities further downstream from severe flooding. Skirting the village of Llanfor , the path of the river takes it past Llandderfel and under the Grade II listed Pont Fawr bridge. The river trends generally east-southeast through the Vale of Edeyrnion, shadowed by the B4401 Bala to Cynwyd road. Leaving Gwynedd and entering Denbighshire the Dee flows beneath other historic bridges at Llandrillo and Cynwyd before arriving at the picturesque town of Corwen . From here the river passes the Iron Age hillfort of Caer Drewyn and enters the Clwydian Range and Dee Valley AONB .

Through its forested valley the course takes it through Carrog , Glyndyfrdwy and Llantysilio , with the Llangollen Railway following the river on its route between Llangollen and Corwen . At Berwyn the river passes over the manmade Horseshoe Falls , before picking up speed on a downhill gradient past the Chain Bridge Hotel and its historic pedestrian bridge. First built in 1814, and later refurbished by Henry Robertson in 1870, it was considered a marvel of early suspension bridge design. In 1928 the original bridge was destroyed by severe flooding and was rebuilt in its current form from original parts in 1929. The course of the river then takes it through Llangollen and under its 16th-century, Grade I listed bridge. The bridge is also a Scheduled Ancient Monument and considered one of the Seven Wonders of Wales . On leaving Llangollen the river continues east, generally skirting the outcropping Karstic limestone exposures of Eglwyseg Rocks ( Welsh : Creigiau Eglwyseg).

Overlooking the river here is the medieval Castell Dinas Brân , a ruined fortress abandoned by John de Warenne, 6th Earl of Surrey in 1282. The river then enters Wrexham County Borough , passing south of Trevor and under Thomas Telford’s Pontcysyllte Aqueduct , of 1805, which carries the Llangollen Canal 120 feet (37 m) overhead. Less than a mile east of the aqueduct at Cefn Mawr , the river is crossed by the Cefn Mawr Viaduct, built in 1848 by Thomas Brassey and carries the Shrewsbury to Chester railway line across the Dee. Beyond this point the river forms the boundary between Wrexham County Borough in Wales and Shropshire in the West Midlands of England. Passing Chirk and the confluence with the River Ceiriog , the river begins to trace gentle meanders on the level ground at the beginning of the Cheshire Plain . The course continues past Erbistock on the Welsh side, and the 5th-century earthwork of Wat’s Dyke on the English, before passing wholly into Wales at Overton bridge.

A couple more miles downstream is Bangor-on-Dee , known for its Racecourse . Until 1974 this area was part of an exclave of historic Flintshire known as English Maelor ( Welsh : Maelor Saesneg). The Dee continues to meander past Worthenbury where it is joined by the River Clywedog . At this point the border between Wrexham and Cheshire West and Chester follows the course of the river. It passes the Cheshire village of Crewe by Farndon , before cutting between Holt in Wales and Farndon in England beneath the 14th-century, Grade I listed Holt Bridge. One of the major tributaries of the Dee, the River Alyn (Afon Alun) crosses the Carboniferous Limestone from Halkyn Mountain and runs down through the Loggerheads area before making its confluence north of Holt. Throughout the length of the Alyn there are numerous swallow holes and caverns and during the summer months long stretches of the river bed run dry. These caves include Ogof Hesp Alyn and Ogof Hen Ffynhonnau .

A significant part of this lost flow reemerges in the Milwr Tunnel , a manmade tunnel, entering the west bank of the Dee estuary and carrying 12 million imperial gallons per day (600 l/s). This tunnel was originally constructed to drain metal mines in Halkyn Mountain. Once the main River Dee approaches the Cheshire border and the Carboniferous Coal Measures , it turns sharply northwards before meandering up to Chester . This long stretch of the river drops in height by only a few feet. The rich adjoining farmland has many remnants of abandoned coal workings and deep claypits used to make bricks and tiles . A number of these pits are now being used as landfill sites for domestic and commercial waste. Approaching Churton and Aldford , the river crosses entirely into England, and passes the grand country house of Eaton Hall , seat of the Duke of Westminster . It then continues past the village of Eccleston and beneath the A55 North Wales Expressway, tracing northwards past the Roman Eaton Road to the Chester suburbs of Huntington and Handbridge before reaching the centre of Chester . In the city centre the river passes and around the Earl’s Eye(s) meadow at Queen’s Park .

In this vicinity, the riverside is used as a recreation area with a bandstand, benches and boat cruises, being crossed by four bridges. The first is the Queen’s Park Suspension Bridge, which forms the only exclusively pedestrian footway across the river in Chester . The second is the Old Dee Bridge , a road bridge and by far the oldest bridge in Chester , being built in about 1387 on the site of a series of wooden predecessors which dated originally from the Roman period. View of the Grosvenor Bridge , taken from the south bank of the river Winter sunrise at Llangollen Above the Old Dee Bridge is Chester Weir , which was built by Hugh Lupus to supply power to his corn mills. Throughout the centuries the weir has been used to power corn, fulling , needle, snuff and flint mills. The same weir was used as part of a hydroelectric scheme in 1911 with the help of a small generator building which is still visible today, used as a pumping station for water since 1951. However the first water pumping station here was set up in 1600 by John Tyrer who pumped water to a square tower built on the city’s Bridgegate.

It was destroyed in the Civil War but an octagonal tower built in 1690 for the same purpose lasted until the gate was replaced with an arch in the mid-18th century. On this weir is a fish pass and fish counting station to monitor the numbers of salmon ascending the river, and also a weirgate for navigating the weir at spring tides. A little further downstream stands the Grosvenor Bridge (designed by architect Thomas Harrison of Chester), which was opened in 1833 to ease congestion on the Old Dee Bridge. This bridge was opened by Princess Victoria five years before she became Queen. The other side of the Grosvenor Bridge is the Roodee , Chester’s race course and the oldest course in the country. This used to be the site of Chester’s Roman harbour until, aided by the building of the weir, the River Dee silted up to become the size it is today. The only curiously remaining reminder of this site’s maritime past is a stone cross which stands in the middle of the Roodee which exhibits the marks of water ripples. To the end of the Roodee the river is crossed by Chester’s fourth bridge which carries the North Wales Coast railway line , before leaving Chester.

This was the scene of one of the first serious railway accidents in the country, the Dee bridge disaster. Railway bridge in Chester, spanning the river between Curzon Park and the Roodee . Photo taken at high tide . Canalised section West of Chester , the river flows along an artificial channel excavated between 1732 and 1736. The work was planned and undertaken by engineers from the Netherlands and paid for by local merchants and Chester Corporation. It was an attempt to improve navigation for shipping and reduce silting. Chester’s trade had declined steadily since the end of the 17th century as sediment had prevented larger craft reaching the city, spelling the end for the Port of Chester. After four years’ work, the river was diverted from its meandering natural course which passed Blacon , Saughall , Shotwick Castle , Burton and Parkgate and up the west shore of Wirral . Instead the new canalised section followed the coast along northeast Wales. During this time, Sealand and Shotton were reclaimed from the estuary : see Sealand, Flintshire#Timeline . Land reclamation in this area continued until 1916.

The river’s natural course can still be determined by following the bank and low bluffs that mark the western edge of the Wirral Peninsula. The manmade channel, which runs in a straight line for 5 miles (8.0 km), passes into Wales and Flintshire at Saltney . On the west shore is Hawarden Airport and the large Airbus factory at Broughton . This region is known as Deeside and contains several heavy industries. From here the Dee passes beneath three road bridges. The first two are adjacent to each other at Queensferry . They are a 1960s fixed-arch bridge carrying the A494 Queensferry to Dolgellau trunk road and its predecessor the New Jubilee Bridge , which is a rolling Bascule bridge completed in 1926. The third crossing, and the most recent, is at Connah’s Quay . The Flintshire Bridge is a fixed cable-stayed bridge . It opened in 1999. Between the second and third road bridges is Hawarden railway bridge at Shotton , originally constructed as a swing bridge but now never opened.

It carries the Birkenhead (Bidston) to Wrexham (Wrexham Central) Borderlands Line over the river. Hawarden Bridge railway station serves the Deeside Industrial Park, Deeside Power Station and the works at Dee Marsh. A footbridge replaced the passenger ferry at Saltney in the 1970s. Estuary Beyond Connah’s Quay the river opens out into the Dee Estuary , forming the northeasternmost section of the North Wales coast and the western coast of the Wirral . Towns along the coast include Flint , Holywell and Mostyn on the Welsh side and Neston , Parkgate , Heswall , West Kirby and Hoylake on the Wirral side. South of Bagillt and Parkgate the Dee Estuary forms the boundary between the local authority areas of Flintshire and Cheshire West and Chester . Northwards it forms the boundary with the Metropolitan Borough of Wirral in Merseyside , North West England . The estuary continues to widen until finally entering the Irish Sea and Liverpool Bay between the northernmost point of mainland Wales, Point of Ayr at Talacre , Flintshire and Hilbre Point, near Hoylake and West Kirby in Wirral , Merseyside .

Hilbre Island , part of Wirral, straddles the mouth of the estuary at this point. The waters of the Dee then converge with those of the River Mersey and Ribble , producing a notable drop in salinity and increase in sediment which can be tracked a considerable distance along the Sefton and Lancashire coasts. The estuary is hugely important for birdlife and has been designated both as an SSSI and as a Ramsar site accordingly. Its value lies in the huge expanses of mud which are exposed between tides and the extensive saltmarsh developed on both sides but principally on the right bank north and south of Neston . The estuary owes its origins to the scouring of a broad channel through the Triassic sandstones and Carboniferous mudstones by glacial ice during successive ice ages to form an iceway . The channel continues inland south of Chester but its higher reaches have long since been infilled with sand, gravel and mud. The process of infilling by mud continues to the present day as the rapid growth of the saltmarsh in the last century testifies, pushing the high tide line further out into the estuary.

Uses The Chainbridge at Berwyn about three miles (5 km) upstream from Llangollen The River Dee at Llangollen , after stormy weather Industry Large parts of the catchment are devoted to agriculture and there a number of abstractions made from the river for summer irrigation. The volumes involved are not however significant. From Chirk downstream, the river valley has supported a wide range of industries that were initially drawn to the area by the presence of coal mines and later by the deep deposits of Carboniferous clays used to make bricks and tiles . The coal industry in particular gave rise to a number of chemical industries some of which survive to this day and which both take water from the river and discharge their cleaned up effluent back into the river. Industries in the valley include commercial chemicals manufacture, wood chip and MDF fabrication, cocoa milling, fibreglass manufacture, waste disposal (in old clay pits ) and a great variety of smaller industries concentrated around Wrexham . The main impact on the river of these industries is their thirst for a dependable good quality water supply.

Currently the wings [4] for the Airbus A380 , which are made at Airbus’s manufacturing factory in Broughton , are taken downriver by barge to the Port of Mostyn because they are too large to be shipped in an Airbus Beluga . [5] However, the dredging of the river for the barge may be responsible for a weakening of the tidal bore . Abstractions There are a number of direct water abstractions upstream of Chester by three water companies and by the canal. The size of the abstraction is very large compared to the summer flow and the flow in the river is very highly regulated through the use of reservoirs to store water in the winter and release it in the summer. The whole system is managed as the River Dee regulation system . Below Chester water is also abstracted as cooling water by the gas-fired power station at Connah’s Quay . Process and cooling water is also abstracted for the paper mill and power station at Shotton . Water sport The Dee used to be a popular whitewater kayaking and touring river (particularly the grade III/IV whitewater section upstream of Llangollen).

It stays high after rain for longer than most British rivers and is paddleable year-round (thanks to the River Dee Regulation System). Canoeing used to be allowed on about twelve weekends per year, and tens of thousands of canoeists descended on Llangollen for recreational paddling (several Dee tours were held every winter), slalom competitions, and wild water races . In 2003, negotiations with the angling associations owning fishing rights on the Dee broke down. The anglers wanted to restrict the numbers of paddlers on the river when paddling was allowed but the Welsh Canoe Association wanted to renew the previous agreement. In November 2004, a protest about the lack of access on the Dee, and to rivers across England and Wales, was held in Llangollen. Following the failure of the access agreement, the Welsh Canoeing Association advises canoeists to use their own judgement about using the river, which in practice means many canoeists use the river at will from the numerous access points along its banks. Canoeing is permitted on one 100 m long rapid, 1 km upstream of Llangollen. Wildwater and slalom races are still held at Serpent’s Tail rapid upstream of Llangollen.

Canoeing and kayaking are also permitted between Farndon and Chester, as this section of the river is tidal and falls under the jurisdiction of Cheshire West and Chester Council. Each July the Chester Raft Race is held on the Dee in aid of charity. The Deva (Chester) Triathlon uses the Dee for the swim leg of the race. [6] The rowing clubs on the Dee are Royal Chester Rowing Club (hosting also Chester University Rowing Club) and Grosvenor Rowing Club . King’s School Rowing Club and Queens Park High School are school-dedicated rowing clubs. All these share the slightly meandering Chester/lower reach before the estuary. Fishing View of the Dee from the famous Grosvenor Bridge in Chester, looking downriver towards Curzon Park . Taken in spring at high tide Same view of the Dee in Chester, looking downriver towards Curzon Park. Taken in summer at low tide. The river has been famed as a mixed fishery with salmon and trout fishing, mostly in the upper waters and a good coarse fishery in the lower reaches.

A major pollution incident in the middle reaches in the late 1990s did extensive damage to the fishery from which it is now largely recovered. See also River Dee - Major Rivers Of The British Isles Major Rivers Of The British Isles There are five rivers with the name Dee situated within the British Isles, one in Cumbria in England, one in the Republic of Ireland, one which flows between Wales and England and two in Scotland. The name Dee comes from the Roman word Deva, which means goddess. Scotland’s River Dee, Uisge De, is situated in north east Scotland and rises on the plateau of Braerioch, a four thousand foot high summit of the Cairngorm Mountains. The river starts life as several small pools and tiered waterfalls known as the Wells of Dee, before travelling for eighty seven miles towards it’s estuary at Aberdeen Harbour on the North Sea. The river is renowned for having the highest elevated source in the United Kingdom and it’s drainage basin at Aberdeen Harbour is home to the largest marine centre in Europe which covers some eight hundred square miles.

The river has several tributaries including the Rivers Muick, Gairn and Lui, Quoich Waters and Coy, Clunie and Geldie Burns. The river is also the site of a small tiered waterfall near it’s confluence with the Geldie Burn, known as the Chest of Dee. The river’s course passes through some of Scotland’s finest heathland and Caledonian pinewood forests, the Cairngorms National Park, the Cairngorms National Nature Reserve and the towns of Aboyne, Braemar, Banchory and Ballater and the City of Aberdeen. The river also encompasses the area of Strathdee, also known as Royal Deeside, which is situated between Ballater and Braemar, so named as it is home to nearby Balmoral Castle. The river has exceptional stocks of salmon and is also renowned for it’s large pools of rapids, making it popular with both fly fishers and canoeists.

The river is spanned by several bridges including the Victoria Bridge at Torry, The King George VI Bridge which carries the B9077 road, The Queen Elisabeth II Bridge in Aberdeen, the Maryculter Bridge situated in the town of the same name and the multi arched Bridge of Dee on the outskirts of Aberdeen, built in 1527 with golden coloured, Elgin sandstone. Another unusual bridge is the St Devenick’s suspension, footbridge situated in an Aberdeen suburb, which was built in 1837. RIVER DEE, CUMBRIA, ENGLAND Images courtesy of Eamon Curry - The River Dee in Cumbria is a tributary of the River Lune which starts life at Dent Head situated along the Dales Way National Trail. The river travels in a northerly direction for about ten miles through the area known as Dentdale, where it goes on to join the River Rawthey at Catholes, near Sedbergh. All of the river's course takes in the green, rolling countryside of the Cumbrian Dales as it passes through the villages of Cowgill, Dent, Gawthrop and Stonehouse.

Some of the old, stone bridges that span the river are the Abbot Holme Bridge at Sedbergh, Bridge End at Stonehouse, Church Bridge at Dentdale and Tommy's Bridge. There is also a small, stone footbridge situated at Cowgill. The river also has a small, tiered waterfall situated just outside Sedbergh. The area along the course of the river is popular with ramblers and hikers. The river is little used by fishermen, despite evidence of trout in it's waters, owing to it's inaccessibility for fly fishing. RIVER DEE, DUMFRIES AND GALLOWAY, SCOTLAND Scotland’s other River Dee, also known the Dee / Ken System, is situated in the south west of the country in Dumfries and Galloway, where it rises on Loch Dee in the Galloway Mountains and travels for thirty eight miles as it makes it’s way through Clatteringshaws Loch, Loch Ken and the Water of Ken, before entering the Solway Firth on the Irish Sea at Kirkcudbright Harbour. The river passes through the towns of Bridge of Dee, Crossmichael, Glenlocher, Kelton, Kirkcudbright, Parton and Tongland.

Thomas Telford built a stone, single arch bridge at Tongland in 1806, shown above, and the river was also dammed at Tongland during the 1930’s to form part of a hydro – electric plant. There is also an interesting four arched bridge at Kelton which was built from rubble masonry during the early 1800’s. The river is renowned for being home to the ruins of Threave Castle, a twelth century, stone walled tower and keep, built on an island in the river, near the town of Castle Douglas. The river has several small tributaries including Tarff Water, the Water of Ken, the Water of Deugh and Shirmer’s Burn. The waters of the River Dee and it's tributaries are renowned for their large population of salmon and sea trout, making the area along the course of the river popular with fishermen as well as ramblers and hikers. RIVER DEE, REPUBLIC OF IRELAND The River Dee in Ireland is a thirty mile long tributary of the River Glyde.

The river's source is located at Bailieboro in County Cavan, it then flows in a north easterly direction until it joins with the thirty five mile long, River Glyde, at the small harbour town of Annagassan in County Louth, where the two rivers go on to flow into the thirty three square mile, Dundalk Bay on Ireland's east coast, along with the River Fane and the Castletown River. In County Meath the River Dee passes through the town of Nobber, before flowing into Whitewood Lake and then passing through the small town of Kilmainhamwood. The river then goes on to flow through the County Louth towns of Ardee, famous for it's sixteenth century, St Ledger's Castle, which is the largest fortified, medieval tower house in the country, and the coastal town of Annagassan. The River Dee has three tributaries, the River Killary, the Gara River and the White River, all of which are known to have stocks of Brown Trout, Sea Trout and Atlantic Salmon.

RIVER DEE, WALES / ENGLAND Image courtesy of AKKE, wikimedia commons The River Dee in Wales - Afon Dyfrdwy - is a sixty eight mile long river which starts life at Llanuwchllyn in Snowdonia. The river travels in a south easterly direction making it's way across the border into England, before changing course to a northerly direction out towards it's estuary, situated between North Wales and The Wirral Peninsula in England, where it drains into Liverpool Bay on the Irish Sea. The river's course takes it through the Welsh towns of Berwyn, Corwen, Llangollen and Wrexham and the English towns of Connah's Quay and Farndon and the English City of Chester. At Wrexham the river sets a natural border between the two countries and at Connah’s Quay the river becomes tidal for it’s last sixteen miles. The river feeds several lakes and resevoirs along it's course, including Bala Lake, just ten miles from it's source, Llyn Brenig, Llyn Celyn and the Tegid Resevoir.

The river has several tributaries including the Rivers Afon Alun, Afon Alwen, Afon Ceiriog, Afon Clywedog, Afon Meloch, Afon Mynach, Afon Tryweryn and the Wych Brook. The Dee is spanned by hundreds of bridges, with the two oldest being the Llangollen Bridge in the town of the same name built in 1345 and the Old Dee Bridge in Chester, originally built around 1387. Other interesting bridges include the rivers newest bridge, the Flintshire Bridge, an impressive, cable stayed bridge built in 1999 at Connah’s Quay, which carries part of the A548 road, the Chain Rail Bridge at Berwyn built in 1814, a medieval sandstone bridge at Farndon and Britain’s largest aqueduct, the Grade I listed, UNESCO World Heritage Site of Pontecysyllte Aqueduct, pictured below, which carries the Lllangollen Canal over the River Dee near Wrexham. The eighteen arch aqueduct was opened in 1805 and was built by Thomas Telford and William Jessop.

The brick and cast iron structure is one thousand and seven feet long and one hundred and twenty six feet tall. Other interesting features of the river include the man made Horseshoe Falls at Llantysilio, constructed in 1808 by Thomas Telford, which are four hundred and sixty feet wide and link the river with the Llangollen Canal, and the Grade I listed Chester Weir, pictured above, originally constructed in 1093 in order to power local corn mills. The river is renowned for being one of the country’s premier fishing locations for catching Atlantic Salmon as well as sea trout, lamprey, freshwater pearl mussels and grayling. West of Chester the river was canalised during the 1700’s in order to alleviate the river’s natural heavy build up of silt. The five mile long channel diverted the course of the river out towards it’s estuary by setting the river on a more northerly course. The River Dee’s estuary is situated between the North Wales coast and the Wirral Peninsular coast and covers an area of some fifty square miles.

The Dee Estuary consists of extensive mudflats and salt marshes and was formed thousands of years ago by glacial erosion.The estuary waters are a haven for wading birds and Atlantic grey seals, resulting in the area being designated as both an SSI - Site of Special Scientific Interest and an SPA – Special Protected Area. The estuary also forms part of Britain's first country park, The Wirral Country Park, which opened in 1973, which also incorporates an estuarine nature reserve and the thirteen mile long, Wirral Way, walking path. The waters of the estuary also contain three uninhabited islands, the largest of which is Hilbre Island, which is an eleven square acre, nature reserve, which can be accessed at low tide. Places of interest on the estuary's Welsh side are the town of Flint, the ruins of the thirteenth century, Flint Castle, the small Port of Mostyn and the sand dunes and lighthouse at Talacre Beach.

Small towns and places of interest on the estuary's English side are the towns and villages of Neston, Parkgate, Heswall, Thurstaston, Caldy and West Kirby and part of the Royal Liverpool Golf Club's links course at Hoylake. There are five lighthouses located along the Dee Estuary, one at Hilbre Island and Talacre Beach in Wales, both of which are fully functioning, two at Hoylake, both of which have been incorporated into local dwellings and one at Leasowe, which is the oldest surviving, brick built light house in the country.
